When visiting a modern grocery store, consumers may find their options seemingly unlimited. Those options abound, whether you typically visit a large-chain grocery store with 20-plus aisles and expansive specialty sections or you tend to go to smaller stores that emphasize organics and other health foods. 

Regardless of where consumers buy their food, soy foods are one option they’re likely to encounter. Many people have undoubtedly encountered soy foods, even if they didn’t realize it. For example, edamame is a common soy food used in various recipes. In addition, a trip to the dairy aisle of a favored grocery store will likely lead to an encounter with soymilk. Given the ubiquity of soy foods, consumers may want to learn the basics of this widely available option. 

What are soy foods?

The United Soybean BoardTM notes that the term “soy foods” refers to a broad category of soybean products consumed by humans. Soy foods include edamame, tempeh, tofu, miso, soy milk, and soy-based meat alternatives. “Adding edamame, tempeh, or tofu to soups, salads, or casseroles can be an excellent way to add protein without adding fat to our diet,” says Laura Warren, MS, RDN.  

How common are soy foods?

Soy foods are more common than consumers may realize. In fact, the Kansas Soybean Commission notes that individuals likely have soy foods in their pantries, even if they aren’t aware of it. Protein shakes and baking flour are two examples of foods that include soy ingredients. 

How healthy are soy foods?

While Warren notes that consuming soy foods two to three times a week can be beneficial, it is important to speak with a physician before making any dietary changes, however insignificant they may seem, because such changes are best made under a physician’s supervision. Physicians can also discuss the latest research on various foods, including soy foods, with their patients.

Regarding the nutritional value of soy foods, the Harvard T.H. Chan School of Public Health notes that there remains ongoing debate. Nutritional scientists often highlight the significant health benefits of soy foods, but also note that some research suggests soy can have adverse effects in certain situations. This has led to hesitancy about recommending soy foods without qualification. This debate underscores the need for people to discuss soy foods with their physicians before altering their diets. 
Soy foods are considered rich in B vitamins, fiber, potassium, magnesium, and high-quality protein. However, the T.H. Chan School of Public Health notes that soy also can have estrogenic properties, which can affect hormone levels in the body. Since no two people are the same, the effects of soy foods on the body are expected to be different among individuals. Research on the effects of soy foods on human health is ongoing, which is another reason why it’s so important to discuss soy foods with a physician before changing a diet.
